Incidence of and Risk Factors for Heart Failure in Patients With Psoriatic Disease: A Cohort Study

To assess the incidence and risk factors for heart failure in patients with psoriatic disease and to describe their electrocardiographic and echocardiographic findings.

A cohort analysis was conducted involving patients with psoriatic disease followed prospectively from 1978 to 2018. Participants were assessed according to a standard protocol every 6 to 12 months. The primary outcome was the time to first event of heart failure, further classified into ischemic and nonischemic heart failure (secondary outcomes). The association between cardiovascular risk factors, measures of disease activity, and heart failure events was assessed using Cox proportional hazards regression. Electrocardiographic and echocardiographic findings associated with heart failure events were described.

A total of 1,994 patients with psoriatic disease were analyzed, with 64 incident heart failure events (38 ischemic, 26 nonischemic). The incidence rate of first heart failure event was 2.85 per 1,000 patient-years. In all events, the most common electrocardiographic findings were atrial fibrillation (22%) and bundle branch blocks (29%). Echocardiogram revealed 37% reduced ejection fraction and 63% preserved ejection fraction. In multivariable analysis, independent risk factors for all heart failure events were ischemic heart disease, adjusted mean tender joint count, adjusted mean swollen joint count, adjusted mean erythrocyte sedimentation rate, adjusted mean C-reactive protein level, and physical function (by Health Assessment Questionnaire) (all P < 0.05). Minimal disease activity state was protective for all heart failure (P < 0.05).

Increased risk of heart failure is associated with a combination of known cardiovascular risk factors and measures of disease activity, particularly in nonischemic heart failure. The effect of inflammation on heart failure may be partially independent of atherosclerotic disease.
